[issue43340] json.load() can raise UnicodeDecodeError, but this is not documented

New submission from Matthew Woodcraft : The documentation for json.load() and json.loads() says: « If the data being deserialized is not a valid JSON document, a JSONDecodeError will be raised. » But this is not currently entirely true: if the data is provided in bytes form and is not

[issue33302] The search for pyvenv.cfg doesn't match PEP 405

New submission from Matthew Woodcraft : PEP 405 says that the pyvenv.cfg file is found as follows: « a pyvenv.cfg file is found either adjacent to the Python executable or one directory above it (if the executable is a symlink, it is not dereferenced), » But in cpython if the executable is a

[issue30755] locale.normalize() and getdefaultlocale() convert C.UTF-8 to en_US.UTF-8

Matthew Woodcraft added the comment: I've investigated a bit more. First, I've tried with Python 3.7.0a1 . As you'd expect, PEP 537 means this behaviour now also occurs when no locale environment variables at all are set. Second, I've looked through locale.py a bit. I b

[issue18378] locale.getdefaultlocale() fails on Mac OS X with default language set to English

Matthew Woodcraft added the comment: That alias (C.UTF-8 to en_US.UTF-8) is surely a bug in itself nowadays. I've filed #30755 . -- nosy: +mattheww ___ Python tracker <http://bugs.python.org/is

[issue30755] locale.normalize() and getdefaultlocale() convert C.UTF-8 to en_US.UTF-8

New submission from Matthew Woodcraft: I have a system where the default locale is C.UTF-8, and en_US.UTF-8 is not installed. But locale.normalize() unhelpfully converts "C.UTF-8" to "en_US.UTF-8". So the following crashes for me: python3.6 -c "import locale;local

[issue16217] Tracebacks are unnecessarily verbose when using 'python -m'

New submission from Matthew Woodcraft: If I run my code using 'python -m' and there is an unhandled exception, the tracebacks include lines from runpy.py (and now sometimes from importlib._bootstrap) which don't provide useful information, and tend to overwhelm the valua

[issue13995] sqlite3 Cursor.rowcount documentation for old sqlite bug

New submission from Matthew Woodcraft : The documentation for the sqlite3 module contains the following statement, under 'Cursor.rowcount': For DELETE statements, SQLite reports rowcount as 0 if you make a DELETE FROM table without any condition. This doesn't happen for

[issue13475] Add '-p'/'--path0' command line option to override sys.path[0] initialisation

Matthew Woodcraft added the comment: The proposed --nopath0 option is something I've wished I had in the past. If this is added, it would be good if it could be given a single-letter form too, because it's an option that would be useful in #! lines (they don't reliably sup

[issue9977] TestCase.assertItemsEqual's description of differences

New submission from Matthew Woodcraft : TestCase.assertItemsEqual uses two different techniques to describe the differences in the inputs that it compares. If the inputs are sortable, it sorts them and then uses assertSequenceEqual to describe the difference between them considered as ordered

[issue9976] Make TestCase._formatMessage public

New submission from Matthew Woodcraft : It would be pleasant if TestCase._formatMessage, or something similar, could be made part of the documented API; I think pretty much anyone writing a custom TypeEqualityFunc is going to end up reimplementing it. (This is the code that makes the

[issue9802] Document 'stability' of builtin min() and max()

New submission from Matthew Woodcraft : In CPython, the builtin max() and min() have the property that if there are items with equal keys, the first item is returned. From a quick look at their source, I think this is true for Jython and IronPython too. I propose making this a documented

[issue5173] "What's new" claims StandardError was removed in 2.6

New submission from Matthew Woodcraft : In the current "What's New In Python 3.0" documentation, under "Changes To Exceptions", it is claimed that the removal of StandardError is "in 2.6 already". But according to the 2.6.1 documentation, StandardErro
